REMOVAL & INSTALLATION



See Figure 1

Before the brake booster is reinstalled, the brake booster pushrod must be adjusted so that there is zero clearance between it and the master cylinder. This adjustment requires the use of a brake booster pushrod gauge such as SST No. 09737-00010 or its equivalent.

  1. If necessary, remove the instrument lower finish panel, air duct and floor mats to gain access to the brake booster linkage.
